TS27M2, TS27M2A, TS27M2B Low-power CMOS dual operational amplifiers Features Wide supply voltage range: 3 to 16 V Ultra-low consumption: 150 A/op typ N Output voltage swing to ground DIP8 Excellent phase margin on capacitive load (Plastic package) Gain bandwidth product: 1 MHz typ Vio down to 2 mV max. (B version) Description D The TS27x2 series are low-cost and low-power SO-8 dual operational amplifiers designed to operate (Plastic micropackage) with high-voltage single or dual supplies. These operational amplifiers use the ST silicon gate CMOS process, providing an excellent consumption-speed ratio thanks to three different power consumptions, making them ideal for low- consumption applications: I = 10 A/amp: TS27L2 (very low power), CC P I = 150 A/amp: TS27M2 (low power) and CC TSSOP8 I = 1 mA/amp: TS272 (high speed) CC (Thin shrink small outline package) The devices also offer a very high input impedance and extremely low input currents. Their main advantage compared to JFET devices is the very low input current drift with temperature Pin connections (top view) (Figure 3).

All values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage. 4. Short-circuits can cause excessive heating and destructive dissipation. 5. R are typical values. th 6. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 7. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of connected pin combinations while the other pins are floating. 8. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. Table 2.
